PIC Xt Osc + Ceramic

hi
with this kind of ceramic osc, should i conect it like a Qz (2 x 18pF) ?
or a direct connexion to osc1/2 without the 2 little caps ?
 

Re: PIC Xt Osc + Ceramic

Yes you have to use some caps. For an 16F77 there is a note on this in the datasheet. In your case (4MHz resonator) Microchip recommends 2 x 33pF.
